Identify the incorrect statement from the following.

The shapes of $\displaystyle d_{x y}, d_{y z}$, and $\displaystyle d_{z x}$ orbitals are similar to each other ; and $\displaystyle d_{x^2-y^2}$ and $\displaystyle d_{z^2}$ are similar to each other.

All the five $\displaystyle 5 d$ orbitals are different in size when compared to the respective $\displaystyle 4 d$ orbitals.

All the five $\displaystyle 4 d$ orbitals have shapes similar to the respective $\displaystyle 3 d$ orbitals.

In an atom, all the five $\displaystyle 3 d$ orbitals are equal in energy in free state.
